CARBURETER.

Specication of Letters Patent.

Patented Nov. 19, 1907.

Application tiled March 13, 1906. Serial No. 305,839.

To all :whom 'it may concern:

Be 1t known that we, JOSEPH GABRIEL PIERRE MARIE MONNIER, a citizen of the Republic of France, and ANTOINE MoIsE l parts.

This invention relates to carbureters, and has for its object to provide a novel construction of carbureter which operates to completely gasil'y the gasolene or other hydrocarbon, and to thoroughly mix the gasified gasolene or other hydro-carbon with the air.

Some embodiments of my invention will irst'be described, and then the novel features thereof will be pointed out in the appended claims.

, In the drawings, Figure 1 is a vertical central section through a carbureter embodying our invention; Fig. 2 is an end view thereof; Fig. 3 is a top plan view; Fig. 4 is a side view of the mixing cone detached; Fig. 5 is a plan of the portion of the casing on which the atomizing-chamber is supported; Fig. 6 is a central vertical section showing a modiied form of our invention; Fig. 7 shows still a third modification.

A designates a tank to contain a quantity of gasolene or other volatile hydro-carbon 'which is to be fed to the atomizing-chamber; This chamber contains a float B carried on a valve-stem C, said stem having at its lower end a valve D which controls the admission of the gasolene or other hydro-carbon to the chamber A.

F designates a nipple to which the supplyl pigs may be connected.

xtending laterally `from the tank A are one or more passages or ducts G which lead into an atomizing-chamber I in which the iuid is atomized and gasied.

In the present embodiment of our invention, the casing of the tank A is provided with a lateral foot 3 on which the atoniizingchamber I rests, and said foot has air-ports J therein leading into the atonIizing-chamber. In Fig. 1 there are two atomizingchambers, one at either side of the tank A. Each chamber has the frusto-conical base portion 4 resting on the foot 3 and the invertedE,frusto-conicaliupperportion 5, to the upper end of which the conduit N leading to the motor is connected. l

I-I designates a nozzle which extendsup through the lower conical portion 4 of the atomizing-chamber, and which communicateswith the duct G.

During the operation of the motor, the volatile Huid in the tank A'is drawn through the nozzle or injector II into the atomizingchamber where it is atomized and mixed with the air which is drawn through the ports J. In order to more completely gasify the atomized fuel and lmix it with the air, we 1 provide the mixing device M which is in the I shape of an inverted frustum of a cone which is open at the bottom and is pro-f vided with a plurality of lateral' apertures 6 through which air enters. The atomizingchamber is provided with lateral air-ports 7 which admit air to the upper end of the atomizing-chamber, said air being drawn through the lateral apertures 6 and thus Y completing the gasification of the and thoroughly mixing therewith.

The amount of air which is admitted through the ports 7 may be re lated by'a suitable valve device K- which 1s pivoted to the atomizing-chamber .and -provided with ports K adapted to register with the ports 7. This valve K may have secured thereto by screws L a rod or other connection which is operated by the driver of the vehicle according to the speed of the motor.

It will be noted that the lower open end of the cone M is smaller than the upper end of the conical portion 4, and as a result part of the current of air which is drawn in through the ports J passes into the open lower end of the mixing cone M with the stream of gasolene, and art of the air asses up on the outside of said cone and is rawn in through the apertures 6 therein. By thus dividing the air which is drawn in to the mixing chamber through the ports J and causing part of the air to be im inged against the stream of gasolene Within the mixing cone M and the rest of the air to be passed up outside of said cone and then through the apertures 6 a better mixture and more complete gasification of the liquid fuel can be secured.4

In the embodiment of the invention shown in Fig. 6 the atomizing-chamber is shown as i 5 5 cylindrical and the desired conical shape is 1'10 and also with other air 'ven to that portion through which the nozzle H extends b,y providing a frustoconical shell H within which the nozzle H is situated. VIn this embodiment of the invention the auxiliary air-ports opposite the mixin cone are designated by 8, and they extenclear around the cylinder I and are controlled. by a valve in the shape of a ring L provided with ports K This valve may be manually controlled by securing thereto an suitable connection, as at L. Itwill be noted that in this embodiment of my invention also the lower open end of the cone M is smaller than the upper open end of the shell H and as a result part of the air which is drawn in through the shell H is delivered directly to the lower open end of the cone, and part is delivered up on the outside of' the cone and passes through the apertures therein. I find that by thus dividing the air which is delivered from the shell H a better mixture can be secured than if' all the air were delivered either through the side or throu h the lower open end. The valvesicontrol ing the lateral ports serve to regulate the lamount of air which is mixed with the gasiied fuel7 whereby the richness o'the explosive charge may be varied.

We may if desired place below the ports J an inlet-chamber` 10 Y which is provided with lateral air-ports 11 ports 12 in its bottom which are automatlcally controlled by a spring-pressed valve 13.

as' shown in FigxjS;

ments of ourinvention, what we claim as new and'desire to secure by Letters Patent 1s z- 1. In a carbureter, an atomizing-chamber having a conical shape at its lower end, and an air-inlet at its bottom, a nozzle extending through the lower conical portion, and an inverted hollow apertured mixing cone having an open lower end situated over the nozzle, said atomizing-chamber having auxiliary air-inlet ports in its side opposite said mixlng cone.

2. In a carbureter, -a nozzle, an openended cone-shaped member, surrounding the nozzle and having air inlet ports in its lower end, an inverted apertured hollow mixing cone having an open lower end which is slightly smaller than the upper end of the cone-shaped member and which s situated closely adjacent thereto, a cas surrounding said cone-shaped member ailli mixing cone, said casing being provided with air inletports opposite the mixing cone, and a valve to control the admission of air to said ports.

In testimony whereof, we have signed our names to this specication, in the presence of two subscribing witnesses.
